11 Claims.

This inventionvrelates generally to register assemblies of heating apparatus for motor-vehicles.

One of the essential objects of the invention is to provide a register assembly wherein provision is made for directing toward either or both the driver and adjacent passenger of the vehicl the warm air that is received from a suitable heater of the apparatus.

Another object. is to provide a register assembly wherein provision is made for adjustably holding in the respective positions desired the directing means aforesaid of the register.

Another object is to. provide a register assembly wherein a defroster for the windshield of the vehicle is carried by and receives its supply of warm air from the body of the register.

Another object is to provide a register assembly wherein the flow of warm air to the register outlets and to the defroster is controlled by individually operable valves carried by the body of the register.

Another object is to provide a register assembly wherein the operating means for the valves are carried by a bracket mounted on the body of the register.

Another object is to provide.v a register assembly wherein the body of the register, defroster supply fitting and bracket just mentioned are constructed and arranged in such a way that they may :be held together by a single screw.

Other objects, advantages and novel details of construction of this invention will be made more apparent as this description proceeds, especially when considered in connection with the accompanying drawings, wherein:

Referring now to the drawings A is the register body, B is the defroster for the windshield, C and D, respectively; are the air control valves for the body and defroster E and F, respectively, are the controls for operating the valves C and D, and H is the supporting bracket for the controls of an assembly embodying-my'invention.

As shown, the :body A of the register has a tubular inlet portion [9 and a segmental or fanshaped outlet portion ll. Any suitable means such as a tube or hose (not shown) may :be used to conduct warm air from a heater of suitable heating apparatus to the tubular inlet portion I ll of the register,while two pivotallymounteddoors or deflectors I2 and [3, respectively, are preferably used to control the flow of air from the outlet portion I l In the present instance there are two laterally spaced outlets M and I5, respectively; in the curved edge of the outlet portion- H of the register. The door'lZ controls outlet l5, while the door 13 controls outlet [4. Preferably these doors are pivotedat their inner ends to a substantially triangular-shaped block or insert. l 8 in the body and aI'e'IPIOVldGd at their outlet ends with knobs or finger pieces H by which they'may bemani'pulated.

By referring to Figures 3", 1'3'and'1 l it will be noted that the pivot portions I3 ofthedoors turn in vertically spaced semi-circular grooves I 9 in the block 16 and are held therein by semi-circular portions 23 of aretainer plate 2|". Anadjusting screw 2'2v extends through this plate 2|" atthe center thereof and threadedly engages the block I6, while other screws 22 extend through the top and bottom of the body A of the register and threadedly engage the block l6. A threaded opening [6 is provided in the block I6 for the screw 22 while threaded sockets l6 and i6, re-

spectively, are provided for the screws 22 Thus, when the adjusting screw 22 is loose, the doors I2 and I3 may be swung about their pivot points as desired. Upon tightening the adjusting screw 22, the doors l2 and I3 will be held in adjusted Positions.

The defroster for the windshield preferably comprises two substantially triangular-shaped heads 36 and 3|, respectively, adapted to be located upon the inner side of the vehicle windshield at the base thereof so as to open upwardly toward the glass thereof, branch air supply tubes 32 and 33 for said heads, and a T-fitting 34 for said tubes. As shown, the stem portion 35 of the fitting is sleeved upon a laterally projecting tubular part 36 of the register body A, and the branch supply tubes 32 and 33 are sleeved upon the lateral arms 3'! and 38, respectively, of the fitting.

The air valves C and D, respectively, for the register and defroster are carried by the body A. Preferably the valve C is pivotally mounted in the tubular portion ll) of the body adjacent the laterally projecting tubular part 36 of the register body, while the valve D is pivotally mounted in the laterally projecting part 35 of the register body.

The controls E and F for operating the valves C and D consist of horizontally slidable finger pieces 46 and M having forwardly extending shanks 42 and 43 adjustably connected to binding posts 44 and 45 carried by crank portions 46 and 41 of the valve pivots 48 and 49.

The supporting bracket H for the controls E and F has a circular portion 50 sleeved on the laterally projecting part 36 of the register body between the latter and the T-fitting 34 and has a rearwardly projecting arm portion 5| provided at its rear end with laterally spaced depending flanges 52 and 53. Bushings 54 for the shanks 42 of the slidable finger pieces are anchored in the depending flanges 52 and 53.

Inasmuch as the bracket H is sleeved on the laterally projecting tubular part 36 of the register body between the latter and the T-fitting 34, it will be apparent that a single screw such as fastening the T-fitting 34 to said tubular part 36 of the register body will suflice to maintain the fitting 34 and bracket H in assembled relation with the register body A.

In use, the control F may be operated to open the valve D so that warm air received by the inlet portion ll) of the register will flow through the fitting 34 and tubes 32 and 33 to the windshield defroster heads 35 and 3|. Likewise, the control E may be operated to open the valve C so that warm air received by the inlet portion iii of the register will flow to the outlet portion ll thereof. Manipulation of the doors l2 and i3 will control the flow of warm air from the register outlets l4 and [5 to the interior of the vehicle body. For example, the doors l2 and I3 may be operated so that warm air will be discharged through outlet l4 only, or through outlet l5 only, or through both outlets l4 and 15, as desired. The adjusting screw 22 may then be tightened to hold the doors l2 and IS in adjusted position.
